The authors found that marital coitus had ceased for a definable period (median=8 weeks) in one-third of a sample of 144 men and 221 women who were relatively young and had been married an average of 11 years. An analysis of factors related to the social background and marital relationship of the respondents indicated that the cessation behavior of men is more highly predictable than that of women and that antecedents of this behavior differ markedly between the sexes. The authors suggest that, even among relatively young couples, marital intercourse is discontinous and problematic.
作者发现，在144名男性和221名女性组成的样本中，三分之一的人处于相对年轻且平均结婚11年的状态，他们的婚内性行为已经停止了一段可明确界定的时间（中位数为8周）。对受访者社会背景和婚姻关系相关因素的分析表明，男性性行为停止的行为比女性更具可预测性，且这种行为的诱因在性别之间存在显著差异。作者认为，即使在相对年轻的夫妻中，婚内性交也是断断续续且存在问题的。
